A card cage for mounting circuit boards comprises lateral panels and an electrically connecting panel extending between the lateral panels. Opposed sets of two spaced rails span the lateral panels and support extruded grille units substantially transverse to the connector panel and the lateral panels to define a cavity for receiving the circuit boards. A plurality of guides formed integrally with each grille unit receive edges of circuit boards inserted in the cavity. Each set of rails and associated grille units define a grille structure of the card cage. A method for forming a grille structure for use in a card cage comprises the steps of forming a support member and support rails. Forming the support member includes extruding a metal piece with a planar portion and a plurality of elongated, U-shaped members carried by the planar portion, cutting the metal piece transverse to the U-shaped members and forming a connecting surface. Forming the support rails includes extruding a metal rail with a receiving structure and cutting the metal rail to form two rails of predetermined length to extend between lateral panels of a card cage. Connecting the opposed connecting surfaces with the receiving structure of the respective supporting rails forms the grille structure.
